" SPECIFICATION forming part of Letters Patent No. 749,608, dated Januar-y 12,1904.-

' I Application filed January 31, 1903. Serial No.141,325. (No model.)

To all whom it may concern.-

Be it known that I, OSCAR Fno'rscnnn, a citizen of the United States of America, and aresident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Windows,- of which the following isa specification. I 1

This invention relates to certain-new and usefulimprovements in windows of that class in which the sash are arranged to rotate on horizontally-arranged pivots as well as to slide inthe ordinary manner. I

One of the objects of my invention is to provide a-sash of this character which will be simple in construction and easy in operation and which 'will be of such a formv that it can readily be made at themills.

'A further object ofmy invention is to provide a parting-bead, which at the same time acts as an eflective weather -strip and which is so arranged as to be capable of being placed in inoperative position inorder to permit the sash to swing on their horizontal pivots.

Other details of my invention will be more particularly set forth in the description follow- 1 in their vertical positions, but the parting-- bead still locked in its inactive position. Figs.

3 and 4 -are horizontal sections showing the combined parting bead and weather-strip,

Fig. 3 showing said bead and strip in its active 'positipnand Fig. 4 showing it in inactive position." In these figures both sashes are shown at the same level in section. Fig. 5 is a vertical section of part of a frame,'showing my combined parting-bead and weatherstrip held outward by its spring in full lines and in its inner position in dotted lines. Figs. 6 and 7 are side elevations of the partingstrips, the .first of said figures showing the strip in its normal position and the other in its inactive position; Fig. 8;is a perspective view of a portion of a sash, showing one of the-minor features of construction. Fig. 9 is a perspective view of a portion of the com'; bined parting-bead and Weatherstrip. Fig. 10 is a perspective view of a bearing for the horizontal pivot Fig. 11 is a vertical section of a window, showing my invention when arranged with metalsash. Fig. 12 is-a horizontal section of the same. Fig. 13 is a vertical section of one of the sides and parts of the top and bottom of a metal sash made in accordance with my improvement, showing my method of pivotally mounting the sash, this figure showing the upper section of the sash removed in full lines and in place in dotted lines. Fig. l i is a similar section of my combined parting-bead and weather-strip when used with a metal construction. Fig. 15 is a detail of-one side of the metal sash, and Fig; 16 is a similar detail of my combined partingbead and weather-strip which coacts with the side of the sash" shown in Fig. .15.

Referring now to the details of the drawings by numerals, and more particularly to. Figs. 1 to 10, inclusive, the numeral l designates the upper, and 2 the lower, sash, which, as represented in these figures, may be made of ordinary construction, but which are preferably provided with longitudinal strips 3 and 4. (Shown in perspective view in Fig. 7.) These strips are preferably formed separately of the sash proper and screwed or otherwise secured thereto and have recesses which leave longitudinal grooves 5 and 6' fora purpose hereinafter disclosed. When a wooden construction is used, I prefer to cut'into each stile 9 two longitudinal grooves 10, extending from 9 top to bottom ofthe stiles, and these groovesmay of course be plowed in the stile during the construction at'the mill. One side of the stile is preferably provided with a closure 11 of any desired form, whilethe other side95 may be closed after the sashes are in position I by means of the usual bead 12." Immediately over that part of each stile between the two gr0qves10 is firmly secureda longitudinal strip 14, which I preferto make separate, 0

. combined parting-bead and weather-strip comalthoughit is easily seen that it'may be made integral, if desired, My combined partingbead and weather-strip fits over and hides this strip 14 and to a limited extent is capable of slid-mg thereon, as will be hereinafter described.- In its preferable embodiment the prises a single piece of metal bent to form two parallel sides 15 and 16, which fit over the 1 strip 14 into the grooves 10. The metal is folded onto itself at each side, forming ribs 17..

and 18 of-double thickness and strength, and between these doubled portions the metal forms a flat portion 19 of about the width of the aforesaid strips 14. This combined bead and strip is, as seen in Figs. 3 to 7 inclusive, secured to the longitudinal strip 14 by means t of 'two or more screws 20 20, and in order to prevent these screws interfering with the easy working of the sash and also that the beads and strips may be held in inactive positions,

i and 16 enter' to a slight extent only into the grooves 10. 'Hence the grooves are deep enough "to pe mit the combined bead and strip to. be pushed against the tension of the springs- 24 almost completely therein, as shown in Fig. 4. To providea construction which permits the combined bead and strip to be held into the position shown in Fig. 4, I form slots 28 (instead of round openings) in the metal above orbelow the sunken'portions' 22 22, as seen in Fig. 9. Hence after the combined bead and stripis pushed inward against the springs 24 itmay be bodily shoved downward into the position shown in Fig. 7, the combined bead and strip .being a trifle shorter than the window-stile to permit this movement, (see Fig. 2,) and now the heads of the two lower screws 20 bear against the flat portions 19 of the combined bead and strip, and thereby hold the same in its inner inactive position. (Shown in Figs.

I 4 and 7.) I havementioned that the twolower screws act thus, for the reason that these two only are formed in the way described, the other or top onebeing formed as shown near the top'of Figs. 6 and 7, where the sunken part extends to the full length of the slot. The two lower screws are sufiicient to carry out the desired purpose.

I will-now refer to Fig. 1, where it will be I seen that on each side of the combined bead and strip is situated a sash-slide 30, there being two of these slides for each sash. These 'to move up and down, as usual.

slides may consist of nothing more than a plain strip of wood;but theyare provided with a centrally-located countersunk opening or recess 31, in which is situated a pivot 32,

(seen best in Fig. 2,) this pivot having a bear-.

ing 33 (seen in Fig. 10) and screwing into the sash itself.. These sash-slides 30are of course the same length as their sash and slide up and down'with them, and when the sashes are .in

their normal vertical positions the slides have no movement 1m ependent of their sashes; but

when the sashes are turned on their pivots, as c seen in Fig. v1, the. slides move up or down, as'the case may be, as the sashes are turned more or less on their pivots. Now by referring to Figs. 3 and '4 it will be seen that when the combined bead and strip is in its normal position the side portions-15 project into the longitudinal grooves 5- and 6, formed between the sash andtheir-strips -3 and 4, and thus prevent the, sash from turning on their pivots, although of course the sash are free In order to swing the sash, the operator first moves both ofthe sashes alongside of each other that is to say, moves the lower parting beads and strips preventor enable the sash to swing they act as eflective weather strips, owing to the fact that the sides 15and'16 enter their grooves 10, and at the same time the doubled edges 17 and 18 enter the grooves Thus the wind or air currents are foreedto take 'a very circuitous path, and I therefore deein this construction of-. the greatest value.

' Although in the ten figu res so far described.

I have described the combined bead and strip as belng made of metal in my wooden window,

I do not limit all my claims to. particular metal, as said head and strip can,' altl 1ongh 'not so advantageously,

be made of wood, if so desired.- Y

I will now describe Figs. 1 1 and -1'4, inclusive,

in which I have illustrated my invention in the form in which I prefer to use it when applied to a metallic window. In this form not only the sash but the frame is also formed of metal butmy present invention does not reside in these parts, except 1n so far as they are adapthead and strip of ed for vuse with my combined parting-Mad and weather-strip. One part of theframe (indicated at 40) corresponds to the stile 9 in Fig. 3'and hasits metal bent to form groovbs 42. similar to the grooves 10 in the aforesaid wooden stile 9. A combined parting-bead and l fore, further description of the operation is un- .65

weather-stri 'i (indicated at 43. see'particularly Figs. 12 and 1.6) is identical with the corre-.

sponding part in my wooden window. It is held in position in a slightly-dilferent manner; however, as plates 44: have to be; provided in whichthe screws 45 (see Fig. 14) finda sup-' port. In the construction shown in these fastened together.

Figs. 11 to 14: the sashes are also formed of metal and are of the particular configuration shown in Figs. 12 and 15. I do not herein claini anything new in the construction of this sash, except in so far as it coacts with the combincd'parting-bead and \VGHtlIOI'rSI/I'II) 43 just described. Of course it is. necessary in making this sash to provide a deep groove or runway 57 for thecombined parting-bead and weather-strip to fit into, this groove or runway being particularly shown in Fig. 15, in which it Wlll be seen thatit corresponds 1n every way to the groove 5 shown in Fig. 8. In order to form this groove or runway in the easiest 1118.111

ner, I form the entire sash of sheet metal, and it therefore consists of a flat part 50, a side part 51, two inclined parts and one fiat part 52, 53, and 54, forming a seat for the glass, and two parts 55 and 56, opposite-to and parallel with the part 51, which form the remainder of the side proper. The two-ends of the metal, are formed to provide the groove or runway 57 just described. \After the partsof the sash are assembled I pivot to each of them on each of theim ertical sides slides 80, (see Figs. 12 and 13,) which are equivalent in every way to the ,slides 30 shown in the first-described form. These metal slides 50 are formed of channel metal, and riveted within the channel are reinforcing-strips 82, giving the channel-iron slides sufficient strength and thickness to permit the slides to be pivoted to the sides of the sash by means of the pivots 85, (see Fig. 12,) whichpivots pass into their re-' inforcing blocks or plates 87, (see Figs. 12 and 13,)slipped' between the thicknesses of the sides of the sash before the sash is entirely Of course it is desirable to form these metal sashes with interlocking meeting-rails73 and 74, and the bottom of one of, the sashes is formed with a flange 70, to

71. (Seen in Fig. 11..)

From the foregoing description it will be seen that I have invented a metal sash whichfulfils all the purposes of the wooden sash de scribed in Figs. 1 to 10, and yet is capable ofcoacting with my combined'parting-bead and weather-strip, and is provided with slides 80, on which the sashes are permitted to swing when said parting-bead and weather-strip is locked in its inactiveposition.

The description of my drawings has been given with such clear attention to details that it is believed the operation of my window is apparent from such description and that,therewhich is secured'a protecting and filling stripix nece sary.
